Correction, I sold my MINI.

 

Ok ok EVERYONE needs to chill out....something funny is becoming way to serious......here have some Kool Aid! OH YEAH!!!

 

For the record me and motorsport have cleared things up!

 

i love Christopher Walken

 

Do I understand that you mfg these pulleys for sale......if so I am interested could you post or PM me some info?

 

First of all, SMOOTHING is done according to the amount you want done. That dyno has a smoothing factor of 5, that I can see. This not a huge factor, but fine, that is conjecture. Smoothing does not affect the AF, at least not grossly. It certainly doesn't change the values which are miraculously flattened.

Now, I don't think Tuls likes you throwing around his name and offering up his car to defend your credibility. Just a hunch .

For the record, in all of this, you have been neglecting to mention at least a couple of things which I know. Namely: Tuls's car had an intake and an exhaust, too. I asked repeatedly if anything else was done to the car. You said, "no."

 

I can attest that Tul's car was a very strong stock car. I went on a fun-run just after he bought it and it was stock still being broke in and Tul's was short-shifting. I had an Alta 15% pulley, Alta intake, and Denso IK22 plugs, running to the redline and he was just slightly short of being as quick as my car was and in some driving/powerband conditions, his was quicker. I have no doubt that the car motorsports3 had was also, like Tuls's, a "strong" car from the factory.

 

Are both these cars 05's

 

How did my poor post about trying to obtain 200whp get to a fighting match. God for adults you guys sure act like little kids. I'm sorry I posted now .

The only thing I have basically figured out is the to obtain 200whp I would have to start with stage 2. I think for the time being I will try and hit 170~175whp until I see the need to hit stage 2.

 

SAE 1.06 means that your actual dyno result was multiplied by 1.06 to get the corrected value of 186.2. So, the dyno actually measured 186.2 / 1.06 = 175.7 whp. That still sounds a bit high to me, but much easier to swallow than 188 whp.

FWIW, on a dyno with good control over IAT, ECT, airflow, etc. the "normal" baseline values seem to be:

'02-'04 MCS: 145 whp (+/- 5 whp)
'05+ MCS: 150 whp (+/- 5 whp)

'02-'04 MCS with 15% pulley: 160 whp (+/- 5 whp)
'05+ MCS with 15% pulley: 165 whp (+/- 5 whp)

I have trouble believing that there are cars that are much stronger from the factory than others since:

A) Helix has probably dynoed more MCSes than anyone else in the country and they haven't seen any of these elusive "strong" stock cars. Likewise, they haven't had any non-turbo MCS that made 200 whp (even cars with lots of mods from lots of tuners with lots of power claims).

B) There's no logical explanation for one supercharged car making much more power than its assembly line siblings. Less power, maybe (leaky bypass valve for instance).

 

Perhaps other people that are dynoing their cars aren't posting the SAE corrected numbers. Those numbers are corrected to take into account for temprature, barometric pressure, humidity, etc. They level the playing field by eliminating variables so that comparisons can be more apples-to-apples. So, if motorsports3 were to dyno his car again in 30 degree weather with a very high barometer and very low humidity, the uncorrected numbers would be much higher, but the SAE corrected numbers would be the same as before.

Why cannot one car be stronger or weaker from the factory than others? Have you ever heard of "tollerance stack-up?" I figured that with the amount of super-analytical people on this board, that would be a widely accepted subject.

Basically, lets say that motorsports3 cylinder head was machined slightly different at the OEM supplier and it had just slightly smaller combustion chambers from when they performed the final finishing on the deck surface. Now, instead of having 50cc combustion chamber, (or whatever the stock combustion chamber is supposed to be), his are 49.7. Now, how about his break in procedure? How about the piston ring end gap? Bearing tollerances? Supercharger rotor/ case tollerances? Etc. Etc. Etc.

That being said, there are cars at the opposite end of the spectrum, too. Cars that are "creampuffs" or a little weaker from the factory. Heck, you even hinted at it in your above post with the "+/- 5hp" reference.

Lots of moving parts operating together, each and ever one of them with machining and assembly tollerances. All of those "pennies" can ad up to a "dollar" here and there.

 

Now we know why M7 no longer posts numbers

FWIW, I have an Alta 15%, Alta CAI, 1-ball exhaust mod, & MTH software and my tires (225/45/ZR17's) hate me for it. I have a hard enough time keeping them planted... I couldn't imagine having 200+whp... I couldn't afford to keep tires on the car.

 

I feel you.....life sucks . Would Toyo like to sponsor my habit?

 

Ya, me too... I've got room for a few more logos!

 

Yep, that's possible. However, other than a misadjusted bypass valve, I don't see any of those factors making a BIG difference in the output of the car, even with all of the "best" factory parts combined. If there are cars like that out there, why haven't any of them showed up on the Helix dyno?

 

You should try calling and talking with these guys not only do they know there stuff they know and car about the consumer. Don't turn this into a bashing post.

Just because "they engineer" there designs and try to come up with new and different ways.

 

Actually they finally started posting numbers on the Cosworth kit once they finally broke 200 wheel horsepower. Of course it took them close to $8000 to do it if you add up the other products from the standard kit to make the needed horsepower.

 

Ehh, you must be kidding? It ran me about 5k with crank pulley including 250 for my second-hand exhaust.

 

I may have misread your post. Who is the "they" you are referring to? M7 or isellem? Did you think I was bashing or others?

My point about M7 is no matter how their numbers look [good, bad, otherwise] people tear them apart. The people who want to believe them do... the people who don't want to believe them don't. Peter spent so much of his time justifying his numbers that he just gave up posting them. It's like deja vu seeing these pulley numbers shredded [whether they deserve it or not].

I own M7 products and have talked with Peter a few times and enjoyed every minute. No bashing here.

 

Where is your 200 whp dyno?

 

What few mods might you make to the new MCS Works GP due out in July. Crank HP supposed to be 118.

 

It seems to me we have seen fluctuations of as much as 5 whp on similar cars which is probably within the +/- manufacturing tolerances/parameters....however, I don't think there is a + 20whp monster off the assembly line. If the +5 whp "monster" is real, that same 5 whp can be very expensive to achieve down the line.

 

I know Tul's car is a 2004. Dunno about the other car.

 

How would you explain this since the reading look WAY over what you would expect?

What sort of measurements were done of IAT and ECT? You have an Alta intake, which yielded quite a bit of power in MSFITOY's testing as well as others that have been posted.
